I have a Windows server (Win 2003) not using AD, just a simple local file server.

My Mac clients can log in fine to the server using SMB in the Connect To Server window on the Mac, and they can access files fine, but I can't find any way of changing their server password from their Mac.

A few years ago, we would go into the Mac's Terminal and type:

smbpasswd -r <serverIPaddress> -U <username>

the server would ask for the current password, then allow the user to specify a new password. But with the last few versions of Mac OS X (Leopard & Snow Leopard?) this doesn't seem to work anymore - and now with Lion smbpasswd isn't even included!

Is there some other technique to change the user's server password on the Mac?

Thanks, I just tested the first method and it does seem to work, although most of our users are not currently authorized to use Remote Desktop. The second method is very clever, but I haven't tried it.
